Description
本発明は、前記課題を解決するための手段として、
空気入りタイヤのピン穴に装着されるスタッドピンであって、
軸心方向に延びる円柱状のボディと、
前記ボディの前記軸心方向の一端側から突出するシャフトと、
前記ボディの前記軸心方向の他端部に設けられ、前記軸心に直交する縦軸を中心として対称であると共に、前記軸心及び前記縦軸に直交する横軸を挟んで縦軸方向に非対称に形成される台座部と、
を備え、
前記台座部は、縦軸が前記空気入りタイヤのタイヤ周方向に沿うように配置され、平面視で、前記縦軸方向の長さが、前記横軸方向の長さよりも長くなっていることを特徴とするスタッドピンを提供する。
The present invention, as means for solving the above problems,
A stud pin mounted in a pin hole of the pneumatic tire,
An axially extending cylindrical body,
A shaft protruding from one end in the axial direction of the body;
The body is provided at the other end in the axial direction of the body , is symmetrical about a vertical axis orthogonal to the axial center, and is in the vertical axis direction across the horizontal axis orthogonal to the axial center and the vertical axis A pedestal which is formed asymmetrically,
Equipped with
The pedestal portion, the vertical axis is disposed along the tire circumferential direction of the pneumatic tire, in plan view, the length of the longitudinal axis direction, that you have longer than the length of the horizontal axis Provided is a stud pin characterized by the present invention.
この構成により、スタッドピンをタイヤのピン穴に装着した場合、ピン穴を構成する内面をボディの外面に密着させることができる。この結果、路面を走行する際にスタッドピンに力が作用したとしても、ピン穴から脱落しにくくなる(耐抜止性の向上)。また、台座部を横軸を中心として縦軸方向に非対称に形成しているので、ピン穴への装着方向によって、特定の方向への耐抜止性を向上できる。これにより、走行開始時、コーナリング時あるいは制動時に、トラクション性能、コーナリング性能あるいは制動性能を発揮させることが可能となる(エッジ性能の向上)。また、縦軸方向での耐抜止性を向上させることができる。 With this configuration, when the stud pin is mounted in the pin hole of the tire, the inner surface constituting the pin hole can be brought into close contact with the outer surface of the body. As a result, even when a force acts on the stud pins when traveling on a road surface, it becomes difficult to come off from the pin holes (improvement of slip resistance). Further, since the pedestal portion is formed asymmetrically in the vertical axis direction about the horizontal axis, it is possible to improve the slip resistance in a specific direction depending on the mounting direction to the pin hole. This makes it possible to exhibit traction performance, cornering performance or braking performance at the start of traveling, at cornering or at braking (improvement of edge performance). Moreover, it is possible to improve the non-breaking resistance in the vertical axis direction.
前記傾斜部と他の部分との境界部分が角部で構成されているのが好ましい。
本発明は、前記課題を解決するための手段として、

を備えていることを特徴とする空気入りタイヤを提供する。
It is preferable that the boundary portion between the inclined portion and the other portion be constituted by a corner.
The present invention, as means for solving the above problems,
A stud pin of any of the above configurations;
A pin hole formed in the tread and in which the stud pin is mounted;
To provide a pneumatic tire characterized by comprising:
